GEORGE ROTTMAN, OF NEW YORK, N. Y.

ENvELor.

To all whom it may concern:

- Be it known that I, GEORGE ROTTMAN, a citizen of the United States,and a resident of the city, county, and State of New York, have inventedcertain new and useful Improvements in Envelops, of which the fol 1 ingthe enevolp closed, and of a simple de vice for securing the band 'sothat it will fit snugly to the envelop, and have no'loose ends hangingfrom the envelop. The-securing means comprises a member slida'ble on theband for takingit up more or lessto adapt it to the envelop underdifferent conditions, and theslidable member is adapted to .be hooked orconnected with a cooperating member which latter preferably is fixed inposition on the envelop. The sliding member is easy -to adjust and thesecuring means as a whole is intended to avoid the annoyance of. thefastening devices com- The fastening device is espe cially advantageousfor use on extension onvelops.

In the drawings forming part of this application,

Figure 1 is an elevation of an envelop embodying my invention in whichvlew, one of the corners is turned back to show the arrangement of thecorner reinforcement,

Fig. 2 is an elevation of the upper portion of the envelop with the flapopened.

Fig. 3 is a perspective view of the band and the slidable member fortaking up or shortening the band.

Fig. 4 is a sectional view, taken on the line 7-7 of Fig. 3. 7

Figs. 5 and 6 are plan views of the front and back of an envelop havinga modified form of closing means.

The closing means shown in Figs. 1, 2, 3 and 4: consists of thefollowing: The band 17 may consist of a piece of string, tape, or anyother flexible material adapted for. the purpose, the word band beinghere used to include any such material. There are three eyelets 18, 19,20 in the flap 16 through which the band is threaded in the mannerhereinafter described. A plate 21 secured to the envelop below the loweredge of the flap has a hook 22 on which the bandmay be hooked.

On the band there is arranged a sliding member 23 which is intended toshorten or lengthen the band. This member is here shown as a platefolded upon itself and having overlapping ends24. On one side the plateis formed into a number of reverse loops or folds, 25,26,27,27., 28,29,30. The ends of the band are tightly pressed'between the walls of theloops 26 and 29 of the plate. Tracing the band from the end held betweenthewalls of the loop 29, it will be observed that it passes around theend of the loop and back between the walls of'the loop 30, emerging atthe upper end of the sliding member. From. the loop 30 the run 31 oftheband passes over the flap 16 and through the eyelet 19, thence outthrough the eyelet 18; from the eyelet18 the run 32 extends down 'tothesliding member and the band then passes through the loop'28 of theslidable member. out'to form a loop 33 for engaging the hook 22. From.there the band passes back through the loop 27 of the sli'dable memberto form a run .34, thence over the flap, through the eyelet 18, underthe flap, out through the eyelet 20, back over the flap to form a runand finally through the loops 25 and 26. The band is tightly held ithese latter loops 25, 26.

From there the band is drawn Specification of Letters Patent. PatentedAug. 3, 1920. Application filed April 23, 1917. Serial No. 163,774. 1

is moved upwardly. This will shorten the runs 31, 35 of the band andpermit the runs 32, 34 to lengthen, so that the loop 33 may reachto thehook '22. After the loop' 33 is fastened on the hook the runs 32, 34 aregrasped in one hand and the sliding member in the other and the latteris moved downwardly on the runs 32, 34. The runs 31, 35 of the band willthus be lengthened, the string being drawn from the runs 32, 34: throughthe eyelets. When the sliding member has been moved down sufficientlythe band will be taut enough to hold the flap close on the envelop. Thefriction on the band where it passes through the loops 27, 28of thesliding member is depended upon to prevent the sliding member frommoving except when manipulated as described above. To release theclosing device the sliding member is simply moved upwardly or away it tothe hook 22 the loop 33 of the band is grasped in one hand and thesliding member I 6 differs from the first form in that the band passesaround the bottom or extension portion ofthe envelop. In this form thehook 22 and the sliding member are the same as in the first form and theband is the same as before except that it is longer and that the eyeletsare positioned diflerently. In this form the eyelets 18, 19, 20corresponding to the eyelets in Fig. lare arranged on the front of theenvelop just below the hook 22. The runs 31, 35 and 32, 34 of the bandpass around the bottom of the envelop, thence over the back and thendown over the flap, to the lower edge thereof. I prefer to thread theband through the openings 36 and 37 in the back of the envelop andnearthe top, in order that the band will remain in place on the envelop.In this form the band and sliding member are manipulated. the same as inthe previous form except that the runs 32, 3 1 are grasped between theeyelet 18 and the bottom of the envelop when the sliding member ismanipulated. By having the band pass around the bottom of the envelopthe latter is prevented from expanding be yond what the contentsrequires.

Havingdescribed my invention, what I claim is t 1. An article of theclass described comprising an envelop having a flap, and closing meanstherefor, said closing means comprising a flexible band, means forengaging the band at spaced positions on the envelop and flap'wherebythe band will extend across the edge of the flap to hold the flapclosed, and slidable means associated with the band for shortening orlengthening the latter between 7 them to resist the movement of thesliding member on the band.

2. An article of the class described comprising an envelop having aflap,,and'c1osing means therefor, comprising a flexible band, meansfor,'engaging the band at spaced positions on the envelop and flap.whereby the band will extend across the edge'of the flap to hold theflap closed, said band comprising a plurality of runs, and one of saidengaging. means including eyelets through which the runs of said bandare adapted to slide, a member fixed to certain of said runs and havingcooperating portions which impinge other runs of said band between themwhereby the slidable member may be moved along said band to tighten orloosen it between said engaging means. I

3. A device of the class described comprising an envelop, and means forholding it closed comprising a hook member'on said envelop, eyelets'onthe envelop spaced from said hook member, a flexible band having aplurality of runs slidably engaging in said eyelets, a plate bent toform loops, said band passing backand forth through the loops of-saidplate and forming a loop 33 for engaging said hook member,'saidbandpassing through said eyelets and extending back to said plate vandsecured thereto, whereby said plate maybe slid along'certain runs ofsaid band to tighten or loosen the band between said hook memberand'sai'd eyelets.

Signed at the city, county, and'State of New York, this 9th day ofApril, 1917.
